An incident that has led to oil spill has occurred on April 20 at Russia’s Arctic Trebs oil field, the regional Emergencies Ministry said on Sunday. “An accident occurred at the oilfield at 5.30 pm Moscow time on Friday, oil began rushing,” a ministry spokesman said. Rescuers arrived on Saturday, and the rush of oil was terminated on Sunday. “There was no fire, none was injured,” he added. In late December, Russia\'s largest crude oil producer LUKoil and mid-sized oil firm Bashneft closed deals on a joint venture and partnership to develop the giant Trebs and Titov oilfields in the Russian Arctic.
